I installed Win7 on my main and when I put SMP on there it didn't seem to work right. It has been down for the past week. I finally got around to installing 2 VMs with Ubuntu 64bit (each see 2 CPU cores). They have the 64bit Linux folding client with -SMP tag. Looks like I'm getting ~1500 PPD with each of them. Might see if I can iron out some more ppd.
